NEEDLE-HOLDER FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed November 16, 1916. Serial No. 131,642.

To all whom it may concern:

Be it known that we, FRANK BEAUDOUIN and THOMAS P. BEAUDOUIN, citizens of the United States, residing in the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Needle-Holders for Talking-Machines, of which the follow-' needle eliminates muchof the rasping, I

scratching unpleasant sounds present when a steel needle is used in tallnng'machines,

but one of the defects and objections heretofore present and which in many instances has rendered fiber needles undesirable has been and is that the sounds and tones which result when such needles are used have been of insuflicient volume. Hence it is one of the objects of our invention to provide a construction of holder whereby when a fiber needle is used the volume of sound reproduced upon a machine shall be ampli fied or increased as compared with what the same would have been had such'fiber needle been used with the form of needle holder heretofore employed.

Our invention also has for an. object to provide means whereby fiber needles may be shortened to a greater extent than at' present and still be satisfactory and desirable for use.

Other objects and advantages of our invention will be pointed out in the detailed description thereof which follows or will be apparent, from such description.

To the end that our invention may be more readily understood and'its practical advantages more fully comprehended and appreciated reference may be had to the accompanying drawing in which we have shown embodiments of our invention in forms of construction at present preferred by us, but itwill be understood 'that changes in the construction may be made within the sco e of the claims hereinafter appended Wit out, departing from our invention.

In the drawin Figure 1 is a 111m: elevation of a sound box, needle arm and holder, the latter embodying our invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a view in end elevation of the holder shown in Figs. 1 and 2 and of the fiber needle in place therein.

Fig. 4 is a central longitudinal sectional view of the holder embodying our invention.

Fig. 5 is a front view in elevation of a modified construction of needle arm and .holder embodying our invention.

Fig. 6 is a side elevation of the same; and Fig. 7 is an end view of a holder showing another modification of construction embodying our invention.

Referring to the drawings, 1 designates a sound box and 2 designates a needle arm having laterally extending arms 3. which are pivotally connected with a bar 4 (or other support) in any desired manner.

In Figs. 1 to 6 inclusive of the drawing, a construction is shown in which the holding element is separable or detachable from the needle arm 2. The said holding element com rises a stem or shank portion 10 which is a apted to be inserted into the opening 11 in the lower end of the needle arm into which heretofore and usually the needles have been inserted. After the stem or shank- 10 has been inserted into the hole 11, it is secured therein by means of a binding screw 12. The lower or outer end of the stem ter- -minates in arms 13 and 14 which are angularly related to each other and which also extend downwardly, as indicated, at an angle to the stem. The latter relationship is very clearly shown in Figs. 1, 2 and 4:. The loweror outer ends of the arms 13 and 14 are joined together by the cross bar 15, from which projects or extends outwardly or downwardly the projection 16 provided with anopening, 17 for the reception of the needle 18.

In the construction shown the needle is triangular and the opening 17 is of the same shape and of a size to permit the needle to be easily inserted. At its lower edge, that is, at the position of the vertex of the trianand is securely held any position to which integral with the arm 2. The lower end of the said arm constituting the needle holder in these figures is provided with the angularly related and downwardly depending arms 13 and 1 1, the cross bar 15 connecting the lower ends of said arms, and

the projection 16 v extending. downwardly from said cross bar in the same manner as the correspondingly numbered parts in Figs.

' 1 to 1 inclusive.

As in the preceding figures a notch 20 is provided at the lower edge or at the vertex of the triangular opening 17.

In Fig. 7 we have illustrated in end view a holder having angularly related and downwardly extending arms 13 and 14, the lower ends of which are connected by a cross plate 15 from which the projection 16 extends. The .latter is provided with an opening 25 .for the reception of the} needle 18. This opening is triangular in shape and does not include a notch such as the notch 20 shown in the preceding figures, so that the needle 18 fits the same closely, although not so closely that it ma not readily be inserted and removed. T e needle in this construction is, as in the preceding forms 'of construction, longitudinally adjustable and is adapted'to be secured in adjusted position by meansof the binding screw 26, the inner binding end of which contacts with a side of the needle, as shown. In the preceding constructions the inner binding end of the binding screw contacts with the upper 'slde of the needle, as is clearly shown.

In the several forms 'of-construction the needle holder comprises the angularly re lated arms 13 and 14:, which together with the base or cross bar 15 constitute a portion of. triangular shape. These arms converge upwardly and inwardly as shown, so that the vertex of'the triangular portion'is situated above and inwardly of the portion of the holder in which the needle is secured. We are unable to say just why or how it is that a needle holder of the construction shown efl'ccts or brings about the improved results accomplished by us, but we do know, as a fact, that by the use of such a holder the volume of sound producedwhen a fiber needle is employed is increased and enhanced so that such nccdles' may be employed in the lay ng of musical compositions in whic t is new necessary to employ metal prises the triangular portion including the arms 13 and 14 and the cross or basal bar 15, we desire it to be understood that holders may be employed embodying our invention in which the amplifying means is not of triangular shape but of some other shape as for instance quadrangular, pentagonal, hexagonal, round, etc. At present we prefer to employ a holder having the triangular shaped amplifying portion or section because we have thus far secured the best results with holders having such triangular portions, although greatly improved results have been secured by the use of holders havingamplifying portions or sections of different construction and shape.

We claim 1. A pivotally supported needle arm for talking machines, comprising a portion having an opening therethrough, said opening extending transversely of the length of said arm and being situated intermediate the lowerend of the said arm and the pivotal point thereof.

2. A pivotally supported needle arm for talking machines comprising intermediate 'its lower end and its pivotal point a portion having. an opening therethrough, said opening extending transversely of the length of the saidarm, and means for securing a needle directly to a portion of the said arm immediately adjacent the lower side of said openlng.

3. A pivotally supported needle arm for talking machines, comprising intermediate its lower end and its pivotal point a poly onal portion, the sides of which surround a correspondingly shaped opening through said portion, said opening extending transversely of the length of the said arm.

4. A pivotally supported needle arm for talking machines, comprising intermediate its lower end and its pivotal point a triangular sided portion having a triangular shaped opening extending therethrough.

5. A pivotally supported needle arm for .talking machines, comprising intermediate its lower end and its pivotal point a, triangular portion having a correspondingly shaped opening therethrough, the base of which portion constitutes the lower end of said arm and the sides of which converge" upwardly and are joined together at their upper ends, the said base being provided with means whereby a needle may be secured thereto.

6. A needle arm for sound boxes on talking machines, comprising a part having an opening therethrough, the portions of said part surrounding said opening being rela: tively small in transverse section, and means for supportin said arm with said portions in a plane su stantially at right angles to the plane of the diaphragm of the sound box and substantially parallel with the plane of the vibration of the needle.

7. A needle arm for sound boxes on talking machines, comprising a portion having a polygonal opening therethrough, whereby sald portion constitutes a frame-l1ke structure, and means for supporting said arm with said portion in a plane extending transversely of the plane of the diaphragm of the sound 'box and substantially parallel with the plane of the vibration of the needle.

8. A needle arm for sound boxes on talking machines, comprising a triangular portion having a correspondingly shaped opening therethrough, the base of which portion is situated at the lower end of said arm and the sidesof which convergeupwardly and inwardly and are joined at their upper ends, and means for supporting said arm with said sides situated in a plane extending transversely of the plane of the diaphragm of the sound 'box and substantially parallel with the plane of vibration of the needle.

In testimony that we claim the foregoing as our invention, we have hereunto signed our names this 15th day of November, A. D. 1916 FRANK BEAUDOUIN, THOMAS P. BEAUDOUIN.
